Abstract : A high value of stored energy (0.41 cal/g) was determined experimentally to persist in oxide dispersed alloys to high temperatures. This high value of stored energy is related to the retained high temperature strength of the alloy in the same temperature interval. Theories of the yield stress which take into account the presence of the dispersoid particles are still inadequate to explain the strengthening observed; suggesting the need for much additional experimental and theoretical work.
